e919233b31 Don't show personalized menu items until users establish a full session
Summary:
Depends on D18792. Fixes T13024. Fixes T89198. Currently, when users are logging in initially (for example, need to enter MFA) we show more menu items than we should.

Notably, we may show some personalized/private account details, like the number of unread notifications (probably not relevant) or a user's saved queries (possibly sensitive). At best these are misleading (they won't work yet) and there's an outside possibility they leak a little bit of private data.

Instead, nuke everything except "Log Out" when users have partial sessions.

Test Plan:
Hit a partial session (MFA required, email verification required) and looked at the menu. Only saw "Log Out".

b04d9fdc0b Add a missing key to PhabricatorFile for destroying Files
Summary: See PHI176. Depends on D18733. We issue a query when deleting files that currently doesn't hit any keys.

Test Plan:
Ran `./bin/remove destroy --force --trace F56376` to get the query.

Ran ##SELECT * FROM `file` WHERE storageEngine = 'blob' AND storageHandle = '23366' LIMIT 1## before and after the change.

Before:

```
mysql> explain SELECT * FROM `file` WHERE storageEngine = 'blob' AND storageHandle = '23366' LIMIT 1;
+----+-------------+-------+------+---------------+------+---------+------+-------+-------------+
| id | select_type | table | type | possible_keys | key  | key_len | ref  | rows  | Extra       |

9777c66576 Allow Phabricator to run with "enable_post_data_reading" disabled
Summary:
Ref T13008. Depends on D18701. The overall goal here is to make turning `enable_post_data_reading` off not break things, so we can run rate limiting checks before we read file uploads.

The biggest blocker for this is that turning it off stops `$_FILES` from coming into existence.

This //appears// to mostly work. Specifically:

  - Skip the `max_post_size` check when POST is off, since it's meaningless.
  - Don't read or scrub $_POST at startup when POST is off.
  - When we rebuild REQUEST and POST before processing requests, do multipart parsing if we need to and rebuild FILES.
  - Skip the `is_uploaded_file()` check if we built FILES ourselves.

This probably breaks a couple of small things, like maybe `__profile__` and other DarkConsole triggers over POST, and probably some other weird stuff. The parsers may also need more work than they've received so far.

I also need to verify that this actually works (i.e., lets us run code without reading the request body) but I'll include that in the change where I update the actual rate limiting.

Test Plan:
  - Disabled `enable_post_data_reading`.
  - Uploaded a file with a vanilla upload form (project profile image).
  - Uploaded a file with drag and drop.
  - Used DarkConsole.
  - Submitted comments.
  - Created a task.
  - Browsed around.

8443366f32 Remove bin/files purge workflow
Summary:
Fixes T12948. See that task for substantial discussion and context. Briefly:

  - This workflow is very old, and won't work for large (>2GB) files.
  - This workflow has become more dangerous than it once was, and can fail in several ways that delete data and/or make recovery much more difficult (see T12948 for more discussion).
  - This was originally added in D6068, which is a bit muddled, but looks like "one install ran into a weird issue so I wrote a script for them"; this would be a Consulting/Support issue and not come upstream today. I can't identify any arguments for retaining this workflow there, at least.

Test Plan:
  - Grepped for `files purge`, got nothing.
  - Grepped for `purge`, looked for anything that looked like instructions or documentation, got nothing.

I don't recall recommending anyone run this script in many years, and didn't even remember that it existed or what it did when T12948 was reported, so I believe it is not in widespread use.

ba4b936dff Use Log In vs. Login when it's a verb

I went though every instances of 'login' I could find and tried to clarify all this language. Also, we have "Phabricator" on the registration for like 4-5 times, which is a bit verbose, so I tried to simplify that language as well.

17fc447503 Don't compute MIME type of noninitial chunks from diffusion.filecontentquery
Summary:
Ref T12857. This is generally fairly fuzzy for now, but here's something concrete: when we build a large file with `diffusion.filecontentquery`, we compute the MIME type of all chunks, not just the initial chunk.

Instead, pass a dummy MIME type to non-initial chunks so we don't try to compute them. This mirrors logic elsewhere, in `file.uploadchunk`. This should perhaps be centralized at some point, but it's a bit tricky since the file doesn't know that it's a chunk until later.

Also, clean up the `TempFile` immediately -- this shouldn't actually affect anything, but we don't need it to live any longer than this.

Test Plan:
  - Made `hashFileContent()` return `null` to skip the chunk cache.
  - Added `phlog()` to the MIME type computation.
  - Loaded a 12MB file in Diffusion.
  - Before patch: Saw 3x MIME type computations, one for each 4MB chunk.
  - After patch: Saw 1x MIME type computation, for initial chunk only.

d450a08890 Support HMAC+SHA256 with automatic key generation and management
Summary:
Ref T12509. This adds support for HMAC+SHA256 (instead of HMAC+SHA1). Although HMAC+SHA1 is not currently broken in any sense, SHA1 has a well-known collision and it's good to look at moving away from HMAC+SHA1.

The new mechanism also automatically generates and stores HMAC keys.

Currently, HMAC keys largely use a per-install constant defined in `security.hmac-key`. In theory this can be changed, but in practice essentially no install changes it.

We generally (in fact, always, I think?) don't use HMAC digests in a way where it matters that this key is well-known, but it's slightly better if this key is unique per class of use cases. Principally, if use cases have unique HMAC keys they are generally less vulnerable to precomputation attacks where an attacker might generate a large number of HMAC hashes of well-known values and use them in a nefarious way. The actual threat here is probably close to nonexistent, but we can harden against it without much extra effort.

Beyond that, this isn't something users should really have to think about or bother configuring.

Test Plan:
  - Added unit tests.
  - Used `bin/files integrity` to verify, strip, and recompute hashes.
  - Tampered with a generated HMAC key, verified it invalidated hashes.

08a4225437 Provide "bin/files integrity" for debugging, maintaining and backfilling integrity hashes
Summary:
Ref T12470. Provides an "integrity" utility which runs in these modes:

  - Verify: check that hashes match.
  - Compute: backfill missing hashes.
  - Strip: remove hashes. Useful for upgrading across a hash change.
  - Corrupt: intentionally corrupt hashes. Useful for debugging.
  - Overwrite: force hash recomputation.

Users normally shouldn't need to run any of this stuff, but this provides a reasonable toolkit for managing integrity hashes.

I'll recommend existing installs use `bin/files integrity --compute all` in the upgrade guidance to backfill hashes for existing files.

Test Plan:
  - Ran the script in many modes against various files, saw expected operation, including:
  - Verified a file, corrupted it, saw it fail.
  - Verified a file, stripped it, saw it have no hash.
  - Stripped a file, computed it, got a clean verify.
  - Stripped a file, overwrote it, got a clean verify.
  - Corrupted a file, overwrote it, got a clean verify.

63828f5806 Store and verify content integrity checksums for files
Summary:
Ref T12470. This helps defuse attacks where an adversary can directly take control of whatever storage engine files are being stored in and change data there. These attacks would require a significant level of access.

Such attackers could potentially attack ranges of AES-256-CBC encrypted files by using Phabricator as a decryption oracle if they were also able to compromise a Phabricator account with read access to the files.

By storing a hash of the data (and, in the case of AES-256-CBC files, the IV) when we write files, and verifying it before we decrypt or read them, we can detect and prevent this kind of tampering.

This also helps detect mundane corruption and integrity issues.

Test Plan:
  - Added unit tests.
  - Uploaded new files, saw them get integrity hashes.
  - Manually corrupted file data, saw it fail. Used `bin/files cat --salvage` to read it anyway.
  - Tampered with IVs, saw integrity failures.

440ef5b7a7 Remove SHA1 file content hashing and make Files work without any hashing
Summary:
Ref T12464. We currently use SHA1 to detect when two files have the same content so we don't have to store two copies of the data.

Now that a SHA1 collision is known, this is theoretically dangerous. T12464 describes the shape of a possible attack.

Before replacing this with something more robust, shore things up so things work correctly if we don't hash at all. This mechanism is entirely optional; it only helps us store less data if some files are duplicates.

(This mechanism is also less important now than it once was, before we added temporary files.)

Test Plan: Uploaded multiple identical files, saw the uploads work and the files store separate copies of the same data.

1e181f0781 Deprecate "file.uploadhash"
Summary:
Ref T12464. This is a very old method which let you create a file on the server by referring to data which already existed in another file.

Basically, long ago, `arc` could say "Do you already have a file with hash X?" and just skip some work if the server did.

`arc` has not called this method since D13017, in May 2015.

Since it's easy to do so, just make this method pretend that it never has the file. Very old clients will continue to work, since they would expect this response in the common case and continue by uploading data.

Test Plan:
  - Grepped for `uploadhash` in Phabricator and Arcanist.
  - Called the method with the console, verified it returned `null`.

873b39be82 Remove PhabricatorFile::buildFromFileDataOrHash()
Summary:
Ref T12464. This is a very old method which can return an existing file instead of creating a new one, if there's some existing file with the same content.

In the best case this is a bad idea. This being somewhat reasonable predates policies, temporary files, etc. Modern methods like `newFromFileData()` do this right: they share underlying data in storage, but not the actual `File` records.

Specifically, this is the case where we get into trouble:

  - I upload a private file with content "X".
  - You somehow generate a file with the same content by, say, viewing a raw diff in Differential.
  - If the diff had the same content, you get my file, but you don't have permission to see it or whatever so everything breaks and is terrible.

Just get rid of this.

Test Plan:
  - Generated an SSH key.
  - Viewed a raw diff in Differential.
  - (Did not test Phragment.)

45b386596e Make the Files "TTL" API more structured
Summary:
Ref T11357. When creating a file, callers can currently specify a `ttl`. However, it isn't unambiguous what you're supposed to pass, and some callers get it wrong.

For example, to mean "this file expires in 60 minutes", you might pass either of these:

  - `time() + phutil_units('60 minutes in seconds')`
  - `phutil_units('60 minutes in seconds')`

The former means "60 minutes from now". The latter means "1 AM, January 1, 1970". In practice, because the GC normally runs only once every four hours (at least, until recently), and all the bad TTLs are cases where files are normally accessed immediately, these 1970 TTLs didn't cause any real problems.

Split `ttl` into `ttl.relative` and `ttl.absolute`, and make sure the values are sane. Then correct all callers, and simplify out the `time()` calls where possible to make switching to `PhabricatorTime` easier.

Test Plan:
- Generated an SSH keypair.
- Viewed a changeset.
- Viewed a raw diff.
- Viewed a commit's file data.
- Viewed a temporary file's details, saw expiration date and relative time.
- Ran unit tests.
- (Didn't really test Phragment.)

2896da384c Only require POST to fetch file data if the viewer is logged in
Summary:
Ref T11357. In D17611, I added `file.search`, which includes a `"dataURI"`. Partly, this is building toward resolving T8348.

However, in some cases you can't GET this URI because of a security measure:

  - You have not configured `security.alternate-file-domain`.
  - The file isn't web-viewable.
  - (The request isn't an LFS request.)

The goal of this security mechanism is just to protect against session hijacking, so it's also safe to disable it if the viewer didn't present any credentials (since that means there's nothing to hijack). Add that exception, and reorganize the code a little bit.

Test Plan:
  - From the browser (with a session), tried to GET a binary data file. Got redirected.
  - Got a download with POST.
  - From the CLI (without a session), tried to GET a binary data file. Go a download.

9326b4d131 Fix some range issues and 32-bit issues with avatar generation
Summary:
Ref T12444. A few issues:

   - `x % (y - z)` doesn't generate values in the full range: the largest value is never generated. Instead, use `x % (1 + y - z)`.
   - `digestToRange(1, count)` never generates 0. After fixing the first bug, it could generate `count`. The range of the arrays is `0..(count-1)`, inclusive. Generate the correct range instead.
   - `unpack('L', ...)` can unpack a negative number on a 32-bit system. Use `& 0x7FFFFFFF` to mask off the sign bit so the result is always a positive integer.
   - FileFinder might return arbitrary keys, but we rely on sequential keys (0, 1, 2, ...)

Test Plan:
  - Used `bin/people profileimage ... --force` to regenerate images.
  - Added some debugging to verify that the math seemed to be working.

Previously, it didn't particularly matter that we don't MIME detect chunked files since they were all just big blobs of junk (PSDs, zips/tarballs, whatever) that we handled uniformly.

However, videos are large and the MIME type also matters.

  - Detect the overall mime type by detecitng the MIME type of the first chunk. This appears to work properly, at least for video.
  - Skip mime type detection on other chunks, which we were performing and ignoring. This makes uploading chunked files a little faster since we don't need to write stuff to disk.

Test Plan:
Uploaded a 50MB video locally, saw it as chunks with a "video/mp4" mime type, played it in the browser in Phabricator as an embedded HTML 5 video.

67084a6953 Support AES256 at-rest encryption in Files
Summary:
Ref T11140. This makes encryption actually work:

  - Provide a new configuation option, `keyring`, for specifying encryption keys.
  - One key may be marked as `default`. This activates AES256 encryption for Files.
  - Add `bin/files generate-key`. This is helps when generating valid encryption keys.
  - Add `bin/files encode`. This changes the storage encoding of a file, and helps test encodings and migrate existing data.
  - Add `bin/files cycle`. This re-encodes the block key with a new master key, if your master key leaks or you're just paraonid.
  - Document all these options and behaviors.

Test Plan:
  - Configured a bad `keyring`, hit a bunch of different errors.
  - Used `bin/files generate-key` to try to generate bad keys, got appropriate errors ("raw doesn't support keys", etc).
  - Used `bin/files generate-key` to generate an AES256 key.
  - Put the new AES256 key into the `keyring`, without `default`.
  - Uploaded a new file, verified it still uploaded as raw data (no `default` key yet).
  - Used `bin/files encode` to change a file to ROT13 and back to raw. Verified old data got deleted and new data got stored properly.
  - Used `bin/files encode --key ...` to explicitly convert a file to AES256 with my non-default key.
  - Forced a re-encode of an AES256 file, verified the old data was deleted and a new key and IV were generated.
  - Used `bin/files cycle` to try to cycle raw/rot13 files, got errors.
  - Used `bin/files cycle` to cycle AES256 files. Verified metadata changed but file data did not. Verified file data was still decryptable with metadata.
  - Ran `bin/files cycle --all`.
  - Ran `encode` and `cycle` on chunked files, saw commands fail properly. These commands operate on the underlying data blocks, not the chunk metadata.
  - Set key to `default`, uploaded a file, saw it stored as AES256.
  - Read documentation.

39afc0f97c Add an AES256 storage format for at-rest encryption
Summary:
Ref T11140. This doesn't do anything yet since there's no way to enable it and no way to store master keys.

Those are slightly tougher problems and I'm not totally satisfied that I have an approach I really like for either problem, so I may wait for a bit before tackling them. Once they're solved, this does the mechanical encrypt/decrypt stuff, though.

This design is substantially similar to the AWS S3 server-side encryption design, and intended as an analog for it. The decisions AWS has made in design generally seem reasonable to me.

Each block of file data is encrypted with a unique key and a unique IV, and then that key and IV are encrypted with the master key (and a distinct, unique IV). This is better than just encrypting with the master key directly because:

  - You can rotate the master key later and only need to re-encrypt a small amount of key data (about 48 bytes per file chunk), instead of re-encrypting all of the actual file data (up to 4MB per file chunk).
  - Instead of putting the master key on every server, you can put it on some dedicated keyserver which accepts encrypted keys, decrypts them, and returns plaintext keys, and can send it 32-byte keys for decryption instead of 4MB blocks of file data.
  - You have to compromise the master key, the database, AND the file store to get the file data. This is probably not much of a barrier realistically, but it does make attacks very slightly harder.

The "KeyRing" thing may change once I figure out how I want users to store master keys, but it was the simplest approach to get the unit tests working.

Test Plan:
  - Ran unit tests.
  - Dumped raw data, saw encrypted blob.
  - No way to actually use this in the real application yet so it can't be tested too extensively.

1049feb0ed Add support to Files for file storage formats, to support encryption-at-rest
Summary:
Ref T11140. When reading and writing files, we optionally apply a "storage format" to them.

The default format is "raw", which means we just store the raw data.

This change modularizes formats and adds a "rot13" format, which proves formatting works and is testable. In the future, I'll add real encryption formats.

Test Plan:
  - Added unit tests.
  - Viewed files in web UI.
  - Changed a file's format to rot13, saw the data get rotated on display.
  - Set default format to rot13:
    - Uploaded a small file, verified data was stored as rot13.
    - Uploaded a large file, verified metadata was stored as "raw" (just a type, no actual data) and blob data was stored as rot13.

  - No-op object updates could fail in the daemons.
  - Questionable data access pattern in the file query coming out of the profile file cache.

f2c36a934e Provide an <input type="file"> control in Remarkup for mobile and users with esoteric windowing systems
Summary:
Ref T5187. This definitely feels a bit flimsy and I'm going to hold it until I cut the release since it changes a couple of things about Workflow in general, but it seems to work OK and most of it is fine.

The intent is described in T5187#176236.

In practice, most of that works like I describe, then the `phui-file-upload` behavior gets some weird glue to figure out if the input is part of the form. Not the most elegant system, but I think it'll hold until we come up with many reasons to write a lot more Javascript.

This is largely residual from the days of one-time-tokens, and can cause messy configuration-dependent bugs like the one in T7789#172057.

37b93f4262 Don't require POST to download LFS files from main domain
Summary:
Ref T7789. If you don't have `security.alternate-file-domain` configured, we won't serve binary files over GET.

This is a security measure intended to prevent `<applet src="..." />` attacks and similar, where you upload some "dangerous" binary, include it in another page, and it gets some of the host's permissions because Java/Flash security models are (or were, in the past) goofy.

Allow them to be served over GET if the client is Git LFS. This is safe; these attacks can't add arbitrary HTTP headers.

Test Plan:
Fetched files over GET with and without the LFS header.

5664c838fb Reduce thumbnail flickering in comment previews
Summary:
Ref T10262. Currently, we always render a tag like this when you `{F123}` an image in remarkup:

```
<img src="/xform/preview/abcdef/" />
```

This either generates the preview or redirects to an existing preview. This is a good behavior in general, because the preview may take a while to generate and we don't want to wait for it to generate on the server side.

However, this flickers a lot in Safari. We might be able to cache this, but we really shouldn't, since the preview URI isn't a legitimately stable/permanent one.

Instead, do a (cheap) server-side check to see if the preview already exists. If it does, return a direct URI. This gives us a stable thumbnail in Safari.

Test Plan:
  - Dragged a dog picture into comment box.
  - Typed text.
  - Thing didn't flicker like crazy all the time in Safari.

439821c7b2 Don't require one-time tokens to view file resources
Summary:
Ref T10262. This removes one-time tokens and makes file data responses always-cacheable (for 30 days).

The URI will stop working once any attached object changes its view policy, or the file view policy itself changes.

Files with `canCDN` (totally public data like profile images, CSS, JS, etc) use "cache-control: public" so they can be CDN'd.

Files without `canCDN` use "cache-control: private" so they won't be cached by the CDN. They could still be cached by a misbehaving local cache, but if you don't want your users seeing one anothers' secret files you should configure your local network properly.

Our "Cache-Control" headers were also from 1999 or something, update them to be more modern/sane. I can't find any evidence that any browser has done the wrong thing with this simpler ruleset in the last ~10 years.

Test Plan:
  - Configured alternate file domain.
  - Viewed site: stuff worked.
  - Accessed a file on primary domain, got redirected to alternate domain.
  - Verified proper cache headers for `canCDN` (public) and non-`canCDN` (private) files.
  - Uploaded a file to a task, edited task policy, verified it scrambled the old URI.
  - Reloaded task, new URI generated transparently.

f9836cb646 Scramble file secrets when related objects change policies
Summary:
Ref T10262. Files have an internal secret key which is partially used to control access to them, and determines part of the URL you need to access them. Scramble (regenerate) the secret when:

  - the view policy for the file itself changes (and the new policy is not "public" or "all users"); or
  - the view policy or space for an object the file is attached to changes (and the file policy is not "public" or "all users").

This basically means that when you change the visibility of a task, any old URLs for attached files stop working and new ones are implicitly generated.

Test Plan:
  - Attached a file to a task, used `SELECT * FROM file WHERE id = ...` to inspect the secret.
  - Set view policy to public, same secret.
  - Set view policy to me, new secret.
  - Changed task view policy, new secret.
  - Changed task space, new secret.
  - Changed task title, same old secret.
  - Added and ran unit tests which cover this behavior.
